15-18 November 2021

Due to the COVID-19 outbreak, this course will be held online




Epigenetic studies on DNA methylation are now possible to do at the nucleotide level genome-wide also in non-model organisms. In this course, we will introduce the different available approaches for obtaining and analysing DNA methylation data, including bisulfite sequencing (BS-seq) with Ilumina and long reads with PacBio and Oxford Nanopore. We will cover all necessary steps to obtain methylation information from high throughput data to statistical analyses used to identify differentially methylated sites and regions. The data will be interpreted in terms of their biological importance in the field of ecology and evolution.


The course will be delivered over the course of four days. Each day will include an introductory lecture with class discussion of key concepts. The remainder of each day will consist of practical hands-on sessions. These sessions will involve a combination of both mirroring exercises with the instructor to demonstrate a skill as well as applying these skills on your own to complete individual exercises.

Target Audience

This course is aimed at researchers and technical workers who are or who will be generating and/or analyzing DNA methylation from reduced representation or whole genome bisulfite sequencing data from IIlumina, PacBio data or Nanopore data. Examples demonstrated in this course will involve primarily non-model organisms with a draft reference genome available and examples of applications of this data type for different purposes will be covered.
